The system also includes a control unit configured to perform at least one of an entry/exit assistance control configured to assist driving of the vehicle or a tunnel driving assistance control configured to assist driving of the vehicle. ## Claims ### Claim 1 A tunnel driving assistance system comprising: a determination unit configured to determine whether a vehicle enters a tunnel and whether the vehicle exits a tunnel while the vehicle is driven; and a control unit configured to perform at least one of an entry/exit assistance control configured to assist driving of the vehicle when the vehicle enters a tunnel or exits a tunnel, based on whether the vehicle enters a tunnel and whether the vehicle exits a tunnel, or a tunnel driving assistance control configured to assist driving from a time at which the vehicle enters a tunnel until the vehicle exits the tunnel. ### Claim 2 (depends on 1) The tunnel driving assistance system of claim 1, wherein the determination unit is configured to: receive navigation information on whether the vehicle enters a tunnel and exits a tunnel, from a navigation provided in the vehicle; and determine whether the vehicle enters a tunnel and exits a tunnel based on the received navigation information. ### Claim 3 (depends on 1) The tunnel driving assistance system of claim 1, wherein the determination unit is configured to determine whether the vehicle enters a tunnel or whether the vehicle exits a tunnel based on an image photographed by a camera provided in the vehicle. ### Claim 4 (depends on 3) The tunnel driving assistance system of claim 3, wherein the determination unit is configured to determine whether the vehicle enters a tunnel or whether the vehicle exits a tunnel based on at least one of a vehicle speed information or a location information of the vehicle. ### Claim 5 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to perform the entry/exit assistance control by restricting a creep torque of the vehicle to be lower than or equal to a preset magnitude when the vehicle enters a tunnel or exits a tunnel. ### Claim 6 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to, when there is a preceding vehicle traveling within a preset distance ahead of the vehicle and when the vehicle enters a tunnel or exits a tunnel, perform the entry/exit assistance control. ### Claim 7 (depends on 6) The tunnel driving assistance system of claim 6, wherein the control unit is configured to perform the entry/exit assistance control by restricting an acceleration torque of the vehicle to be lower than or equal to a preset magnitude when the vehicle enters a tunnel or exits a tunnel. ### Claim 8 (depends on 7) The tunnel driving assistance system of claim 7, wherein the control unit is configured to, when a distance between the vehicle and the preceding vehicle is reduced, restrict the acceleration torque of the vehicle to be lower than or equal to the preset magnitude. ### Claim 9 (depends on 7) The tunnel driving assistance system of claim 7, wherein the control unit is configured to: control at least one of acceleration or braking of the vehicle to maintain a distance between the vehicle and the preceding vehicle to be greater than or equal to a preset distance; and perform the entry/exit assistance control by increasing the preset distance when the vehicle enters a tunnel or exits a tunnel. ### Claim 10 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to perform the tunnel driving assistance control by controlling steering of the vehicle to prevent the vehicle from deviating from a lane until the vehicle exits a tunnel after entering the tunnel. ### Claim 11 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to perform the tunnel driving assistance control by performing vehicle body stability control when the vehicle changes a lane until the vehicle exits a tunnel after entering the tunnel. ### Claim 12 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to control a display unit provided in the vehicle to output a broadcast of a preset channel until the vehicle exits a tunnel after entering the tunnel. ### Claim 13 (depends on 12) The tunnel driving assistance system of claim 12, wherein the control unit is configured to, when information on transmission of a disaster broadcast is received through the preset channel, control the display unit to output a broadcast of a preset channel. ### Claim 14 (depends on 1) The tunnel driving assistance system of claim 1, wherein the control unit is configured to: confirm whether an assistance control function is activated by a user of the vehicle; and when the assistance control function is activated, perform at least one of the entry/exit assistance control or the tunnel driving assistance control. ### Claim 15 (depends on 1) The tunnel driving assistance system of claim 1, wherein the determination unit is configured to: recognize a tunnel in front of the vehicle; and determine whether entry to the recognized tunnel is blocked through at least one of a navigation or a camera provided in the vehicle. ### Claim 16 (depends on 15) The tunnel driving assistance system of claim 15, wherein the control unit is configured to, when determining that entry to the recognized tunnel is blocked, output information on the entry blocking of the recognized tunnel through a display unit provided in the vehicle. ### Claim 17 (depends on 15) The tunnel driving assistance system of claim 15, wherein the control unit is configured to, when determining that entry to the recognized tunnel is blocked, restrict a creep torque of the vehicle to be lower than or equal to a preset magnitude. ### Claim 18 (depends on 15) The tunnel driving assistance system of claim 15, wherein the control unit is configured to, when determining that entry to the recognized tunnel is blocked, restrict an acceleration torque of the vehicle to be lower than or equal to a preset magnitude. ### Claim 19 (depends on 15) The tunnel driving assistance system of claim 15, wherein the control unit is configured to, when determining that entry to the recognized tunnel is blocked, restrict a vehicle speed of the vehicle to be lower than or equal to a preset magnitude. ### Claim 20 (depends on 15) The tunnel driving assistance system of claim 15, wherein the control unit is configured to, when determining that entry to the recognized tunnel is blocked and that a vehicle speed of the vehicle is lower than or equal to a preset reference speed, stop the vehicle.
